R&B star Rihanna has revealed a new duet with the ex-boyfriend who beat her horribly on the eve of the 2009 Grammy Awards. The new Rihanna duet with the man who assaulted her is titled “Nobodies Business”, which is obviously a slap in the face to those who have accused Rihanna of setting a bad example by intimately associating with a man who beat the holy hell out of her.
